Cable Supported Bridges: Concept and Design下载

In the family of bridge systems the cable supported bridges are distinguished by their ability to overcome large spans. At present, cable supported bridges are enabled for spans in the range from 200 m to 2000 m (and beyond), thus covering approximately 90 per cent of the present span range. For the vast majority of cable supported bridges, the structural system can be divided into four main components as indicated in Figure 0.1: (1)the deck (or stiffening girder); (2)the cable system supporting the deck; (3)the pylons (or towers) supporting the cable system; (4)the anchor blocks (or anchor piers) supporting the cable system vertically and horizontally, or only vertically, at the extreme ends.
